CAR-COUPLING.

SPECIFICATION forming part of Letters Patent No. 516,943, dated March20, 1894.

Application filed November 28,1893. Serial No- (N0 m L To aZZ whom itmay concern:

Be it known that LJAMES COOPER ROSE, of Aspen, in the county of Pitkenand State of Colorado, have invented certain new and useful Improvementsin Oar-Couplings; and I do hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it appertains to make and use thesame.

This invention contemplates certain new and useful improvements incar-couplings and it has for its object the production of improved,simple and highly efficient means for holding the coupling pin elevatedand cause the automatic lowering thereof upon the entrance of acouplinglink and also to hold the latter in proper position ready for coupling.

A further object is to render the pin support and link-holder capable ofbeing readily removed and a new one substituted in case of accident. v

The invention consists of a car coupling having its chambered drawheadprovided with approximately J shaped slots 0r grooves in its side wallsin which is designed to lit the trunnions or rounded corners of the pinsupport, which latter can be readily inserted in place and quicklyremoved.

The invention further consists of a drawhead having a U-sha'pe openingin its top, a coupling pin designed to move in and be guided by saidopening, said pin having an offset or shoulder at its lower end, and apivoted support for said pin which will hold the latter elevated andwhen the pin is dropped through the opening of a coupling link will bearupon the latter and hold it in a horizontal position.

The invention also comprises the details of construction, combinationand arrangement of parts, substantially as hereinafter fully set forthand particularly pointed out in the claims.

In the accompanying drawings:-Figure 1 is a vertical longitudinalsectional view of my improved car-coupling. Fig. 2 is a similar view ofthe chambered drawhead. Fig. 3 is a plan view. Fig. 4 is a front endview.

Figs. 5 and 6 are, respectively, views of the pin and the supporttherefor.

Referring to the drawings, A designates the drawhead, having a chambera, the bottom of which has a transverse ridge or shoulder a across itsouter edge. In theinner surface of the side-walls of this chambereddrawhead are opposite corresponding slots or grooves 03 which extendfrom the outer end of the drawhead inwardly and upwardly and are thencurved forward, terminating in rounded ends a the whole being ofapproximately J shape. In the top of the drawhead is a U-shape opening bwhich is surrounded by an extension I).

B is the coupling pin which is of U-shape in cross-section and designedto fit and slide in the U-shape opening I). At its lower end this pin isprovided with an offset or shoulder b O is the pin support andlink-holder, the same holding the pin elevated prior to coupling andautomatically allowing the latter to drop through the opening of a linkupon the entrance thereof, said link being held in a horizontal positionby the weight of said support and holder. This support and holder has adiagonal central opening (1, two curved sides d, cl, connected at'theirlower ends by a widened cross-piece d and at their upper ends by across-piece (:1 the ends of which latter are rounded to form trunnions02 The latter fit in the rounded ends of slots or grooves a and thusform the pivots for the support. 7 The under side of the lowercrosspiece d is curved or partly rounded, as shown, and its upper sideis beveled, as at e, extending through opening (1. The under side of thetop cross-piece d is likewise beveled, as at a, corresponding to thebevel of the lower cross-piece. The upper cross-piece at that part overthe opening is thus reduced to form a shoulder e on which rests theshoulder of the lower end of the coupling pin. The beveled portions of.the cross-pieces permit the coupling pin to drop through opening (1 whenthe holder or support is 7 moved rearward. When thelatter is so moved byan approaching link it will not only permit the lowering of the pinthrough the link-opening but will also bear on the inner end of thelatter and hold it horizontally so that in the event of coupling withanother drawhead the link will be properly positioned. The coupling pinwhen lowered is held in place by its lower reduced end fitting in acorresponding opening f in the bottom of the drawhead.

The advantages of my invention are apparent to those skilled in the artand it will be specially observed that the gravity holder or support forthe coupling pin also serves as a holder to keep the link in ahorizontal position. Another and important advantage is the removabilityof the gravity support. The latter is, of course, liable to be'worn orini jured by the force of the link of the approaching drawhead, and inthat event by means of my invention the holder can be readily removedand a new one substituted.

A coupler constructed in accordance with my invention is extremelysimple and inexpensive and not liable to readily get out of order or bederanged.

I claim as my invention-- 1. The herein-described improved car coupling,comprising the chambered drawhead having a U-shape opening in its top,the gravity holder or support pivoted in said drawhead and having acentral diagonal opening, and the coupling pin of U-shape incross-section having a shoulder at its lower end normally in engagementwith said gravity holder, substantially as set forth.

2. The herei n-described improved oar-coupling, comprising the chambereddrawhead having an opening in its top and inner inclined slots orgrooves in its sides extending from the outer end thereof and curved attheir upper ends into approximately J -shape, the pin-holder or supporthaving trunnions fitted in said slots or grooves and provided with acentral opening and a shoulder, and the coupling pin movable in saidopening in the top and having a lower shouldered end designed to engagesaid shoulder of said holder or support, substantially as set forth.

3. The combination with the chambered drawhead having an opening in itstop and bottom, a ridge or shoulder extending across the forward edge ofsaid bottom and slots or grooves in the sides extending from the outerend inwardly and upwardly, terminating in curved ends, the removable pinholder or supporthavingacentral opening,alowerwidened end and trunnionsat its upper end fitting in said slots or grooves, and the pin movablein said openings in the drawhead and holder or support, substantially asset forth.

In testimony whereof I have signed this specification in the presence oftwo subscribing witnesses.
